0.62 ct Natural Unheated Pink Sapphire – Round Cut

A natural 0.62 carat pink sapphire in a round cut, completely unheated and untreated, AGCL certified (Report #M263602, "No Indication of Heating"). At 0.62 carats in a round cut, this is a practical earring center stone and small pendant solitaire scale in pink sapphire's warm, romantic color. The round brilliant-style cut returns strong light for the weight, making the pink vivid and active even at this sub-carat weight. Unheated pink sapphire is notably rarer than the heat-treated material that dominates the commercial market, since heat treatment is the industry norm for pink sapphire.

Rarity Analysis

A handful of factors combine to make this 0.62 ct pink sapphire a genuinely uncommon specimen, even though its size keeps the price accessible.

• Color: A warm, romantic pink with good saturation for a sub-carat stone — the round brilliant-style faceting keeps it visually active rather than washed out.
• Size: compact, accent/small-centerpiece size
• Cut: note the distinctive "Flower Cut" faceting as a point of interest — a pattern rarely seen on stones at this price point
• Treatment: Unheated / Untreated — a meaningfully rarer specification than the heat-treated pink sapphire that dominates the commercial market
• Clarity: Loupe Clean is a strong grade, giving the stone a clean, eye-clean face-up appearance
• Documentation: note honestly this stone lacks a stated origin — the AGCL report confirms treatment status but does not identify a country of origin
• Combined effect: an unheated, independently certified pink sapphire with unusual faceting is a rarer combination than its modest carat weight and price might imply

Buying Guidance

A few practical points to weigh before purchasing this stone.

• Best uses: well suited to stud earrings, a small pendant solitaire, or as an accent stone in a three-stone or halo ring design.
• Setting considerations: at 5.08 x 5.06 x 3.18 mm, this stone suits a low-profile or protective setting that shields the girdle during daily wear.
• Certification: AGCL Report #M263602 documents "No Indication of Heating" — keep this report with the stone for insurance and resale purposes.
• Origin: no origin is stated on the certificate or in our listing; buyers who require a documented origin should factor that into their decision.
• Try Before You Buy: if you are considering this stone for a custom ring, we recommend viewing it in hand or discussing options with us before committing to a setting.

One of a Kind

This is a single natural gemstone, not a manufactured or mass-produced item — no two sapphires are exactly alike, and once this stone sells, this particular listing will not be restocked.

Care of Round Pink Sapphire

Sapphire is durable (Mohs 9) but should still be cared for thoughtfully. Because this stone is unheated and untreated, it can generally tolerate ultrasonic or steam cleaning better than heat-treated material — but as with any gemstone, clean with warm water, mild soap, and a soft brush as the gentlest option. Store separately from other jewelry to prevent surface scratches, and remove the stone before activities involving harsh chemicals or impact.
